App integration

The BlackBerry 10 OS provides the invocation framework to bring powerful cross-app
integration to the platform. You can use the invocation framework and cards to
greatly enhance the user experience and functionality of your app.

The invocation framework facilitates inter-app communication. The
framework allows your app to start other apps from within its UI, preserving user
focus and ensuring optimal multitasking and app flow. You can also integrate your
app with apps that are included in the BlackBerry 10 OS (also known as core apps). For example, you can integrate with
apps such as File Manager, Pictures, Music, and BBM, and you can
invoke these apps when you need them.

Cards enhance the invocation framework's capabilities. Cards allow you
to open a particular screen of another app as a card, instead of opening the full
app. Cards use fewer system resources and offer a great user experience.

The invocation framework also includes other features that make your app easier to
use and more tightly integrated with other apps on the device. You can add your app
as an entry to different menus (such as the context menu and target selection menu),
allow your app to be invoked using active text, and enable your app to be the
default app for certain types of content.
